Hi everyone new to the forum here hoping for some help. I have an issue with my factory led taillights the passenger taillight doesnt illuminate also the passenger front halo light does not work. I have blinker brake and hazards just no running light or tail light. Ive checked all fuses for bcms all were good. Any help would be greatly appreciated

You can trace the wire harness out of the taillight down under the bed and verify the connection is clean and complete but unfortunately you probably need an entire tail light assembly.

I bought a new assembly already because my other one i knew was bad. I cracked the lens and got water in it thats why i was hoping it was a short or bad fuse. I will check harness tonight and let you know. Thank you for the response

I traced back harness all looked good. Even plugged in the left light to the right same problem so the issue is in the truck because both works work fine when hooked up to drivers side. Is there a bcm that controls just the right side of ghe truck? Because halo light on front is out as well

I couldn't tell you if there was I've never seen a wiring diagram for the circuit. If you can find one online or buy a service manual you'll be able to tell.

I think it’s cheaper just to replace the OEM LED factory harness just to make sure it’s not the harness, dealership sells both for 70$, so one side should Be around 35$ I would buy that before spend on another taillight. But I also have a passenger side Ltz taillight for sell if u needa replacement HMU with a PM if you need it we can talk price.

Hmmmm damn wonder what the cause of this since it’s the front and back passenger side doing it, sounds like the daytime running lights (DRL LED) not working maybe a fuse? Maybe Phil might know @pgamboa

      Some Assembly is Required

      By Grumpy Bear · Posted

      Average Assembly 4.8%   That's the likelihood of a light duty vehicle reaching 250,000 miles. Link below has the stats on this. Among pickups the 350 series (Dodge)  and higher (450 Ford) are most likely and nothing American built in the lighter trucks pegs a number higher than the overall average.  200K and up is the stomping grounds of Asian vehicles. Toyota Sequoia the leader at 39.1% probability.      https://www.autoweek.com/news/a68886903/vehicles-most-likely-to-last-over-250000-miles/   Likelihood drops dramatically at 100,000 miles of reaching even 150,000 miles. 250,000 is deep in the tail of the curve.    I've been told by the 'experts' that I don't need oils of the caliber I use. My high viscosity is damaging my motors. Ash content it to high and WILL foul plugs and kill cats and O2's. I don't need that much ZDP; my choice is over added and not cutting edge. I change it to often. I baby them to much.    Three Honda's reached 200K + and none used oil. All Red Line motors. All sold to friends or family. One Toyota reached 300K using oil, Pennzoil. Dizzy 300K using QSUD until it cashed the rings at 80K then whatever but often ever since. Did you know this engine still sports the OEM timing chain and is dead silent? Pepper spitting into the wind short of 200K, Red Line and changed often. Uses zero oil. A HPFP and a pinion seal. Still using most parts it left Fort Wayne with. So 50% of my vehicles have gone past 250K and 100% of the last half dozen past 200K. Of these two using "shelf oils' did so using abnormal oil and the four that used a premium boutique oil did not. There might be something there the experts have missed. 🤔

      “Service Emission System” & “175 miles until “65 MPH Max Speed”

      It's not that it sits for extended periods. I drive it every couple of weeks. However, I did consider draining the DEF and replacing it.    Don't you get a "Poor quality DEF warning" if its bad?

      Try draining the def and relacing with new if it has been sitting for a long time. Def does go bad after a little while.

      2015 Silverado with HUD retrofit/upgrade.

      Thanks @Viktorrocks15 if you are still out there.   I followed your instructions and worked out great, went to the scrap yard and procured 2016 escalade cluster, hud, bezel, and switch. Got lucky and found a Camaro in the u-pull with the HUD bezel.   I made my own harness with these diagrams: https://www.gmupfitter.com/wp-content/uploads/2022/10/23_Escalade_Escalade_ESV_Electrical_Body_Builder_SM_en_US_2022OCT25.pdf   I used escalade cluster because its the best one that will work IMO. Still need to get it programmed but it looks really good.
